What is stereo?

There are now two system of high fidelity, monophonic (monaural) and stereophonic. Monophonic is a system that starts from one microphone and is fed through a single high fidelity set. Stereophonic is a double system. Two separate microphones are placed at different sides of the orchestra and two different systems are used to keep the two signals or channels separated. Two separate speakers are used, placed on different sides of you room. Stereo is much like 3-D photography, two slightly different sound reach your ears giving you a new dimension in sound.

Acoustic Research AR Turntable "Legend"

 From many years Acoustic Research revolutionised record players by designing our own. It was the world's first belt-driven suspended-subchassis turntable and 'sounded' better than others, long before the hi-fi fraternity appreciated such things.
Years ahead of its time, in concept and performance, it formed the model which was to be emulated the world over. Both turntables are belt driven and offer 33and 45 rpm speeds, changed simply by manually moving the belt. Each comes with a non-resonant acrylic dust cover.
The EB-101 uses a vinyl-covered particle board plinth and combines a superb sonic performance with a very smart appearance at a highly affordable price.
And AR's solutions still hold true.
That's why, when we re-designed and re-launched our turntable as the Legend it became an instant success with Audio critics the world over.
But it's not magic which makes the unique AR sound. That's down to engineering - Acoustic Research style. We place a lot of emphasis on lostening tests to achieve optimum reproduction of music's  timbres, rhytms, textures and nuances. In short, we aimed for listener involvement and satisfaction. Though we place a high priority on listening tests we use the very latest digital test equipment to track down and eliminate any unwanted to track down and eliminate any unwanted vibrations which can interfere with the music.

Both of our current turntables work on the same principles, even the lower-cost EB-101. They incorporate high-quality components:  heavy cast, two-piece platters for spedd stability, close tolerance main  bearings for overall sound precision and bass clarity and carefully designed, slightly different, suspension systems to eliminate the music muddling effects of acoustic feedback.
